Are there any health risks associated with eating fresh berries ?

Yes. Berries are grown in soil, where they may pick up harmful bacteria from manure-based fertilizers. Berries also are hand-picked and subject to additional handling during processing, providing additional avenues for contamination.
Depending on how they are grown, harvested, and processed, fresh berries may harbor the hepatitis virus and pathogenic bacteria such as E. coli O157:H7 and salmonella. Because their rough surface is difficult to clean, strawberries especially encourage viral and bacterial growth. Under moist conditions, berries also can grow mold that can cause illness.  Freezing does not kill the bacteria and viruses associated with berries. Considering these facts, careful handling and thorough cleaning of berries is of utmost importance to enjoy them safely.
